An arrangement includes a holding device for primary packaging containers including: a first component including first receptacles and spanning a first component plane; and a second component including second receptacles and spanning a second component plane. The first component and the second component superimpose one another such that each primary packaging container can be detachably accommodated in one of the first receptacles and the second receptacles such that the first component and the second component together restrict movement of the primary packaging container in one of the component planes and in a direction which is perpendicular to one of the component planes. For each of the first receptacles, there is one of the second receptacles which has a minimum distance from the first receptacle and, for each of the first receptacles, the minimum distance is predetermined by the second component, a third component of the holding device, or both.

Aspects of the disclosure relate to an article carrier (90; 190; 390; 490) for packaging one or more articles and a blank (10; 110; 210; 310; 410; 510) for forming the carrier. The carrier (90; 190; 390; 490) comprises a main panel (12; 112; 212; 312; 412; 512) having one or more article retention structures (RT1, RT2) for receiving and securing the main panel (12; 112; 212; 312; 412; 512) to a respective article (B). The carrier (90; 190; 390; 490) comprises a side panel (18, 20; 118, 120; 218, 220; 318, 320; 418, 420, 518, 520) hingedly connected to the main panel (12; 112; 212; 312; 412; 512) by a hinged connection. The hinged connection between the main panel (12; 112; 212; 312; 412; 512) and the side panel (18, 20; 118, 120; 218, 220; 318, 320; 418, 420, 518, 520) is defined, at least in part, by a curved or arcuate fold line (13, 15, 17, 19).
